Based on Edward Snowden’s revelations, opposition to National Security Agency (NSA) spying has spread across the world, upsetting diplomatic relations and threatening shifts in global power balances. However, as Cyril Mychalejko reports, the NSA network also includes an equally far-reaching, though lesser-known operation called the Open Source Indicators (OSI) Program. The OSI Program involves “academics working at the behest of a research branch of the NSA”—the Intelligence Advanced Research Projects Activity, or IARPA—who analyze and interpret online data collected by other government agencies and contractors in order to predict future events, such as political protests, pandemics, resource shortages, mass migrations and economic crises.
